DESK STAND.

Application filed September 2, 1920.

To all whom it may concern.

Be it known that I, ERNEST A. BOHLMAN, a citizen of the United States of America, residing in Chicago, county of Cook, and

a State of Illinois, have invented certain new and useful Improvements in Desk Stands, of which the following is a specification.

My invention relates to telephone desk stands which are provided with calling devices such as are used for controlling automatic switches.

At present there are different types of calling devices which have different mounting centers, and owing to this fact, the same it desk stand will not accommodate the different types of calling devices- To overcome this objection I have devised a desk stand and a combined adapter and protector which permits the same desk stand to receive the different types of calling devices. An object of my invention, therefore, is to provide an improved desk stand and a combined calling device adapter and protector for use with such desk stand.

An objection found with certain types of calling devices is that, should the substation desk stand be dropped or some object dropped upon the setting member of the calling device, the actuating or setting memso her would be distorted or bent out ofshape. Now, when the calling device is put to use and the setting member rotated, the distorted o-r bent portion of the said setting member engages the finger stop and prevents an operation of the same. To overcome this objection, my adapter is made in the form of a ring which rests between the desk stand base and the calling device. The protector is provided with a pair of upwardly extending flanges diametrically opposite and which extend forward past the face of the setting member so as to protect the same against damage.

For a better understanding of my invention, reference may be had to the accompanying drawings, in which like reference characters in the several views denote like parts, and in which Fig. 1 is a side elevation of my desk stand base, having attached thereto a call ing device and an adapter and protective ring;

Fig. 2 is a plan view of Fig. 1;

Fig. 3 is a sectional view along the line 33 of Fig. 2; r

Serial No. 407,640.

Fig. 6 is a perspective View of the adapter and protective ring. i Referring now more in detail to my invention as illustrated in theaccompanying' drawings, itcomprises the desk stand provided with a suitable base 2 and a standard member 3. The base 2 is provided with an irregularly shaped orifice 4 for purposes as will presently be described. The combined protector and adapter P comprises a ring-shaped member '5 and a pair of forwardly extending arcuate shaped members 6 and 7 diametricallyopposite each other and integrally formed with the ring member 5. The ring member5 is also provided with three downwardly extending lugs 8 intogrally formed with the said ring member 5 and to which certain types of calling devices or'impulse' transmitters CD are secured.

The diameter of the ring member 5 and its arcuate flanged members 6 and 7 is of a size to permit the calling devices to be placed therein as illustrated in Figs. 1 and 2. The calling device CD which is illus trated in the'drawings is provided with a mounting plate 9, upon which the inechanism of the device is secured and with the usual actuating or setting member 10. The calling device CD is provided with suitable extensions 11, and when the calling device CD is used in association with the adapter and protectorP, the said device CD is set in the protector P with the arcuate flanged members 6 and 7 extending forward past the face of the setting member 10. When the calling device is in position within the member P, its extensions ll'register with the lugs 8 of the adapter P. Screws 12 pass through suitable openings in the extensions 11 of the calling device CD and havescrew-threaded engagement with suitable tapped orifices 13 in the downwardly extending lugs 8 of the adapter Pfas clearly illustrated in Fig. 3 and thus secure the calling device CD to the adapter P. The adapter P and calling device CD as a whole can'now be mounted to the base 2 of the desk stand, and the ring member 5 of the adapter P, when the calling device CD lit is inserted into the opening 4 in. the base 2, rests upon the peripheral surface 20 around the said opening 4. V Theopening 4 perm ts the mechanism of the calling device CD to extend into the interior of the base 2 so that the usual electrical connections may be made with the said calling device. When the adapter P and calling deviceCD are in 'ate fianged'membersfi and 7 Which extend forward beyond theface of the setting member 10 protect it against accidental damage due to the i stand being inadvertently dropped, but do not interfere in anyway with the proper actuation of the setting member 10. 7

Now, when my desk stand is usedwith the type of calling device which does not have the downwardly extending lugs 11, it

is placed directly on the surface 20 of the desk stand and fastened thereto by means of screws which extend upwardly through the orifices 21 and the lower orifice 1'6 ofthe stand, into the "mounting plate of the calling device, which is. provided'with tapped orifices to receive the said screws.

From the foregoing it is thus seenlthat when one type of calling device is fused which is provided with tapped orificesin'its mounting, the device is placeddirectlyon the desk stand and the fastening screws pass directly through orificesin the desk'stand into the tapped orifices in 'the mounting plate of the calling device; while, whencall- I ing devices 'of'the'j type provided with lugs are to be used with my desk stand, thecalling device is fastened directly to the combined adapter and protector P, which in turnis fastened to the desk stand.

What I claim as new and desire to secure by United States Letters Patent, is:

1. The combination of a telephonefdesk stand of the character described, a calling device of one character for direct attachment thereto, a calling device of a'second character, a device for attachment to said desk stand adapting the calling device of the second character to be attached to" the desk stand, and a pair of members "formed in tegrally with said device for protecting said calling device of the second character against injury. 7

'2. The combination of a telephonedesk stand and calling devices of two'difi 'erent characters, a combined adapter and protector for connection to said desk stand,'-o'ne calling device being adapted to be directly contector.
